yANTISKID DEVICE,

i v Application filed November 3, 19824. Seria1,No.'747,f598.

To all whom it amg/concern.' Y Y Be it known that I, HERMAN lNEUMANN, citizen of the United States, residing at New York city, inthe county of-NewpYork and State of New York, have invented newv and useful Improvements in AntiskidDevices, of which the'followmg 1s a specifica*- tion.

This linvention relates` to anti-skid de# Another object of the invention is thefpron visionofja device which is collapsibleand which `is adiu'stable to wheels of Yvarious diameters -and which will lit the' wh-eel in a Y neat and snugmanner so as vnotv to Adetract from the attractive app'earance'of the ve-y hicle. Another object of an anti-skid `device which may be folded in a compact manner when not-in fuse to perniit'the Same to-be carried within thevehicle for instant use in an emergency. 4 l YI'Vith these and other-objects` in View, the inventionresides in certain noveleonstruetion and combination andv arrangement of parts-the essential featuresvof which 'are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying draw-y ing, in which Figure 1 is a side'elevation of a vehicle wheel with my invention applied thereto. Figure 2 is a top plan view of the same.

Figure 3' is a transverse sectional view on the line 8-3 of Figure 1. l

Figure 4- is a side elevation of kmy device in a collapsed position. Y

Figure 5 is a detail view of the manner of connecting the meeting ends of the device when in position upon a wheel.

Figure 6 is a detail view of a modified form of connectingmeans, showing the parts prior to being brought to lookin position.A

Figure 7 is a similar view ut showing the position of the parts when locked.

Figure 8 is a detail sectional view on the line 8-8 of Figure 7.

Referring more particularly to the drawing, the lreference numeral 10 designates, a vehicle wheel of the usual well-known oonresidesY in the construction,

struc-tion, .and which includes a tire 11', a

rim 12, Vanda felly113, and torwhichmy in! vivention shown'iny its entirety as atl 14 is attached; i -v y My attachment comprises arplurality of crosslinks y which are pivotally connected together at their',nieetiI-i'gendsy as at .16

^ and midway between their en'dsas atV 17.

AAny number of links may be' employed depending-'f upon 7 the circumference Vof the wheeland the-same are slightlyk curved to The links vs 'ni'igly fit theV contour of the tire.

serve; to provide.an-'attachm-entbaseol lon the Y lazytong principle and maybe expanded ,orcontracted according toy the occasion.

' For securing the devicetothewheel I pror vide two separate` means 18 andl9, the llatter ineans serving to connect themeeting ends of the device, and the former acting, to lock thegdevice aboutfthetire to prevent creeping of the same;

'Y `The@ means 18 comprises arfplurality of metal lstrips 20 of a vshape to snuglyY surround` the sides of the tire, rim and `Vfelly as shown in Figure of thevdrawing The st ripsvare arrangedin pairs diametrica'llyz oppo'site each kother :and .extend between certain spokes'lof the'wheel. v Each strap or [member 20 is connected Y.with the pivot'l yof certain links. The heads of the pivots 116@ and V17H coact with removable pins22 carried by the links for providinga tread surface capable of resisting any skidding actionof the wheel when inrmotion. VThe straps are each formed witha leg 23 liav.

ing an opening24 adjacentthe vfree endv i* and the legs engage the sides of the --felly and extend inwardly of the same, to permit bolts 24 to be inserted through aligned openings in the opposed'straps when "the structure is in position upon the wheel. AdLv 4 ditional gripping straps 20 are 'interposed between the straps 20 and 26 which only V,engage the tire and rim and which co-act with the said straps 20 and 26 for preventing lateral movement of the device upon they of straps 26 formed on the end links'l
